  • Product description: SP-165 (diameters 76-165 mm) steel pipe manufacturing machine process is for 21-89 mm diameters round tube,127x127mm square tube or 100x150mm rectangular tube,the thickness is 2.0-6.0 mm based on the

SP165(76-165mm) steel pipe manufacturing machine process is a series of steel pipe manufacturing process that builds longitudinal weld seam pipe with steel strips of certain width. It starts by uncoil and flatten the slit steel coils into steel strips. The flattened steel strips will be inserted into the forming machine and the rollers in the machine will bend the strip to a round pipe shape. The round steel pipe manufacturing machine. then be sent into the weld box where the pipe is welded by a high frequency or solid state welder. The steel pipe machine be formed to expected shape (round/ square/ rectangle etc) or size in a sizing machine. Finally the pipe will be cut to length and bundled.

Step 3: Strip Accumulator

Function: storage strip to keep continue production.
2 Types: Horizontal / Vertical

Advantage: Horizontal type can be larger storage. Vertical type is much cheap and small space occupied.
